Method and apparatus for continuously winding filamentary material

ABSTRACT

A method and apparatus for winding successively onto a plurality of spools a filamentary material, such as wire, which is continuously fed without interruption when the winding changes from one spool to another spool. A pair of spools are provided beside and parallel to each other with the winding taking place at any given instant on one of the spools. When this one spool has almost been filled the traverse which distributes the filamentary material along the spool is shifted from this one spool to the region of the empty spool while a deflecting roller is shifted to an operative position for deflecting the filamentary material into a loop around the empty spool. Each of the spools has, at an end, an auxiliary spool where a cutter cuts the filamentary material to terminate the length thereof which is wound onto the filled spool. The shifted deflecting roller is returned to its starting position so as to release the loop for movement onto the empty spool and the windings continue thereon. The operations are then repeated with the new spool after the previously empty spool has become almost filled.

While there are many already known methods and ap paratus for winding; filamentary material such as'wire onto spools, allof these known methods andapparatus suffer from serious drawbacks. Thus, according to onesknown wire=reeling: method and apparatus for'continuouslywinding wire onto sue cessive reels, as shown in LLS. PatfNo.=2,932';462 there is'an' overflow orv overrunning of :the wire from a'spoolor'reel-onto the empty spool which is next'to be filled by means of a guit l'e which movesback and forth andtwhich is actuated bya relay in order-to deflect the path of movement'ofth'e'wire to the reel 3 or spool onto whichthewire starts to wind aftera previousspool has been filled. With this method" and apparatus" the transfer from one spool which is filled to the next'ernpty spool which is to be. filled 'onlytakes I place when" the" guide has moved beyond the end flange of the empty spool as'well as'th'e neighboring end flangeof the filled spooli Aside-from'th'e fact that this known type of construction isexceedinglycomplex'; it"

cannot be used for-arrangements where spools-are situated beside and parallel to each'otherrand-isonly:suitable for use with constructions where'the several spools are'coaxiallyfar ranged one after the other alongacommtmaxis.

In particular it is an object of the prsent invention to provide a'meth'od and apparatus whicli' will enable all of these operationsto take' place without any interruption i'n the feedin'gloftlie filamentary material to the spools tobe wound thereon: V

Thus,-it'is*an object of the" invention to provide-a method and apparatus which will retain all of the advantages'whichac crue in connection with winding on'to individual spoo'ls such as; for-example, the provisionof'an elongated aridu'ndair'iaged starting end of'thewinding, so that this latter end, when 'n'e'ce's sary, can be welded "or otherwise fixed to an end of the wire from another spool to provide I substantially" continuous spool lengths from a plurality of spools. 7

Moreover, it isan object of the invention to providea method andapparatus'which will enable the speed' o f rotation" of the spools to be relatively high as contrasted withthe speeds 'ofrotation which can be achieved with known methods" and' apparatus;- so that *agreater output is achieved providing" fora moreeconomical operation of the entire installation;

FIG. 6 is a partly sectional schematic transverse view of the structure of FIG. 5 taken along the line Vl-VI of FIG. 5 in the direction of the arrows.

DESCRIPTION OF A PREFERIRED EMBODIMENT The method and apparatus operate with a pair of parallel spools situated beside each other as illustrated in the drawings. These spools are supported for rotary movement in any suitable bearings on a machine frame 1, and the spools 2 and 3 are supported for rotary movement insuch a way that their axis 4 and 5 are spaced from and parallel to each other. The spools are driven so as to be rotated about their axis to wind the filamentary material, suchas wire or the like, thereon from any suitable well-known drive. As is apparent from the upper part of FIG. I, the spool 2 is situated at the a side of the apparatus while the spool 3 is situated at the b side thereof. The drives which are operatively connected with the spools will, in a wellknown manner, rotate the spool 2 in a clockwise direction and the spool 3 in a counterclockwise direction, as viewed in FIG. I. These directions of rotation are also indicated by the arrows in FIG. I.

A traverse carriage 6 is situated at an elevation higher than the spools for moving back and forth parallel to the axes thereof for distributing the wire in suitable convolutions onto the spools in even layers where the convolutions of the filamentary material are closely located one next to the other. Such traverse mechanisms are well known. In addition, however, the traverse 6 is capable of shifting from a location from one side coacting with one spool to a location at the other side for coacting with the other spool, and for this purpose the traverse mechanism 6 has a pair of reversing rollers the right one of which coacts with the filamentary material when the mechanism 6 is in the region of the spool 2 while the left roller coacts with the filamentary material to guide it to the spool 3, as indicated by the dotted line illustration of the traverse mechanism 6 in FIG. I. The shifting of the traverse mechanism 6 from the a side to the b side and back again to the 0, etc., is carried out in any suitable manner.

In the space between the pair of spools 2 and 3 there are wire-engaging components7 and 8 horizontally shiftable in a direction parallel to the spool axis from the rest position shown for the component 7 in FIG. 4 to the operative position shown for the component 8 in FIG. 4. Thus, any suitable fluid under pressure can actuate a piston in a cylinder so as to hydraulically or pneumatically displace the wire-engaging guide components 7 or 8 between their rest and operative positions. The component 7 coacts with the spool 2 in the same way that the component 8 coacts with the spool 3.

In addition there are situated in the space between the pair of spools 2 and 3 a pair of wire deflecting rollers 9'and 10- respectively shiftable parallel to the direction of shifting of the components 7 and 8 also by way of a suitable pneumatic or hydraulic structure, asis apparent from FIG. 4. In this case also the deflecting roller 9 coacts with the spool 2 in the same way that the deflecting roller 10 coacts with the spool 3. Additional wire-deflecting rods or th'e'like' II and 12 are situated between the pair of spools, and these components also coact v respectively with the spools 2 and 3. The wire-guiding components II and 12 may remain stationary and extend vertically in contrast to the horizontal direction of shifting movement of the components 7 to 10. While components 7 and 8 may be in the form of rollers having vertical turning axis,the deflecting rollers 9 and 10 respectively have horizontal turning axis which are parallel to the axis of the spools 2-and 3.

A pair of rotary drums I5 and I6, eccentrically arranged with respect to spools 2 and 3, respectively, are situated in the region of the drive motors I3 and 14 which by suitable beltand-pulley drives serve to rotate the drum 15 about its axis 21 which is parallel and spaced from the axis of the spool 2 and the drum I6 about its axis 22 which is parallel and spaced from the axis of the spool 3. These rotary drums l5 and 16 respectively fixedly carry radially extending arms 17 and 18. The free ends of these. arms respectively support for free rotary movement swingable guide rolls l9 and 20, these rolls being swingable together with the arms 17 and 18 about the axis 21 and 22 respectively, the drums l5 and 16 are turned by actuation of the motors 13 and 14. Each of the rollers 19 and 20 is provided at its periphery with a groove of V-shaped configuration, for example, for reliably receiving and guiding the wire.

The arms 17 and 18 are shown in their starting positions in FIG. 1. In order to limit the swinging of these arms in clockwise and counterclockwise directions, respectively, as viewed in FIG. 1, suitable limit switches are provided. Thus, in association with each swingable roller 19 and 20 is a limit switch including a pair of stationary contactsK bridged by a bridging conductor Kb carried by each of the arms 17 and 18 and engaging and bridging the space between contacts K when each arm reaches its end position. The arm 17 is shown in its end position in dotted lines in FIG. 1 at the left thereof, as well as in FIG. 3 at the left thereof, and it will be noted that in this position the bridging member Kb bridges the space between and engages the left pair of contacts K for actuating the limit switch to terminate the operation of the motor 13 when the arms 17 reaches the end position shown at the lower left portion of FIG. I. In the same way during counterclockwise swinging of the arm 18 its extent of swinging will be terminated by closing of the circuit between the contacts K at the right of FIG. 1 upon being bridged by the electrically conductive strip Kb carried by the arm 18 so that in this way this right limit switch serves to terminate the operation of motor 14.

Each of the main or primary spools 2 and 3 is provided with an auxiliary spool extending from an end of the primary or main spool. Thus, the main spool 2 has an auxiliary spool 23 coaxial therewith and extending as far as adjacent to the'arm l7, and in the same way the spool 3 has an auxiliary spool 24 fixed to and extending coaxially therefrom between the arm 18 and the end flange adjacent thereto. These end flanges of the spools which are adjacent to the arms 17 and 18 form flanges in common with the main and auxiliary spools. The auxiliary spools 23 and 24 are respectively provided with inner diameters, at their cylindrical cores, which are equal to the core diameters of the spools 2 and 3. However, the flanges 25 and 26 of the auxiliary spools are of a smaller diameter than the flanges of the main spools.

Each of these smaller flanges carries at its surface which is .directed toward the main spool a cutting means in the form of of the spool 2. In the same way it is possible to radially adjust the location of the cutting means 28 from the axis 5 oithe spool3.

The cutting means 27 coacts with an anvil 31 to cut'through the wire, and a wire-engaging element 30 (FIG. 5) deflects the wire to locate it in the path of movement of 'the cutting com ponents 27 and 31 to be cut thereby.

The above described'structure ofthe invention operates,- inaccordance with the method of the invention, as follows:

As is particularly apparent'fromFlGS. 1 and 2,- when the parts are in the condition illustrated, the spool 3is almostfilled. The path taken by the wire Dris indicated by the solid relatively dark line in the drawings. Thus, the wire Dr coming from any suitable source is first guided around a guide roller of the traverse mechanism 6. This mechanism 6; when the spool 3 is almost completely filled, is shifted from side b to side a of the apparatus so that it will now be located at the upperleft position shown in FIG. 1. This will result in the guiding. of the wire around the right roller of the traverse mechanism 6; as viewed in FIG. 1, whereas the wire was guided around theleft roller of the traverse mechanism when woundonto the spool'3' until the latter was almost completely filled! 7 From the traverse mechanism-thewire Dris deflected in the manner most clearly apparent from FIGS. 2 and4 around-the guide 8 which has been pneumatically or hydraulically displaced to its operative position in-a direction-'parallel-to the" axes 4 and 5, and from the guide 8the'wire-willbeguided around the vertical guide 12 soas to continue tobe wound-- onto the spool 3 without any interruption during'the last 'orterminal phase of the winding of the wire onto the spool 3.

This guide 8 when shifted to its operative-position serves to-' deflect the wire from the traverse mechanism fitransversely across the end flange of the spool 2 which is in'common with the auxiliary spool 23 to a. location situated beneaththe swingable guide roller 19. Thus, the guidelZ teams with the deflecting roller 8 to'prevent the .wire from'beingdisplacedfrom the spool 3 during the tenninal part of the winding of the wire onto the spool 3. During this phase of the operation preparations are going forward, asdescribed above and below,

for starting the winding onto the spool 2 so that the winding of the wire will continue withoutinterruption as will be apparent from the description below.

After the wire has thus been deflected bythecomponent-S to the position of FIG. 2 extending beneath the swingable guide roller 19, the deflecting roller 9 ispneumaticallyor hydraulically shifted from the position of FIG. 2 into the posi-' tion of FIG. 4 where it becomes situated beneath the wire t'erminalph'ase of the winding thereon. This operation is particularly appar'entfromFlGS. 3 to 5. lt is only to be noted that for the sake olclarity in the illustration the guide roller 20 carried-by the arm l8and shown in FIG; 3has not been illustrated in FlG. 4'. in this way it is possible to more clearlyillustrate the pathtake'n by the wire as it travels ,to-thespool 3 duringthe terminal phase of the winding thereon to the spool 3.

As soonas theswingabl e roller 19 has reached its end'ppsition; as determined by the limiting switch K,Kb', the wire-engaging element 30 presses the wire into the path of'movement of the anvil cutter 27 to be engaged thereby, and now this member'29 coacts' with the steel-cutting component 31' for cutting through the wire, as is illustrated m'ostclearly in FIG. 5 This will, of course, provide a free end for thewire so as to terminatethewinding thereof onto the spool 3. At the same time thewire which continued to be fed around the traverse mechanism 6 will continue to wind onto the auxiliaryspool 23 until the deflecting roller 9 has been returned in a direction opposite" to thatillustrated'in FIG. 4 to its starting position. These operations can, forexarnple', be controlled by uni'llus trated timing relays which control and determine the proper sequence of the operations.

The result of the retraction of the roller 9 back to it's starting position is that a loop of wire will no longer be capable" of formingaround' the roller'9 and around the flange which is" common to the spool 2 of the auxiliary spool '23. Thus, the wireloop, which previously-extended around this flange, falls and the normal-winding of the wire on the primary spool 2 commences. V

A'tthis instant, the control structureactuates the motor 13 for rettiming the arm 17 and the'roller 19 back to their starting positions illustrated in- FIG. 1; At the same time the wire deflecting guide=8 is retumedto its starting positiomNow, the completely filled spool 3 can be removedand replaced by a new empty spool in a well-known manner.

When the spool 2 is almost filled all of the above operations are repeated inthereverse direction so as totakeplace with this new-spool'which'replaces the previously filled spool 3, so that'now'thetraverse mechanism ois 'shifted from the a side to the b side'and in a completely-analogous maniier all of the above operations are repeated for the empty spool which is now situated at the'location of the illustrated spool 3. Thus, without interruption in the feeding of the wire to the traverse mechanism and from the latter'to the spools the wire is wound completely onto one; spool, and then the winding iss'tarted on the-adj0iningspoo| in a fully automatic manner as described above.

I claim: 1.111- the method for'continuo'usly winding'elongated fila mentary material',isuch as wire or the like, onto one of a pair of parallel spools which are situated beside each other while a traverse carriage distributes the elongated material along the which in turn extends beneath the roller' l9,"so--that howthewire which extends beyond the flange of spool 2, which is in common with spool 23, extends betweentherollers 9 and 19."

The motor 13 is now actuated through any-suitablecontrol structure so as to swing the arm 17 in a clockwise-direction, as} viewed in FIGS. 1 and 3, up to the dotted line position shown at the lower left portions of FIGS-.1 and-3 where the limit ing guide roller 9 to form a loop which extends around'the roller 9, which hasbeen shiftedto. its operative-position, onto the auxiliary spool 23, as is particularly apparent from FIG. 4.

 5. The combination of claim 4 and wherein said swingable arm has an axis of rotation which is parallel to but displaced from the axis of the empty spool which is about to be filled so that the swingable arm turns eccentrically with respect to the empty spool.
 6. The combination of claim 5 and wherein said auxiliary spool has one end flange in common with the empty spool and distant from the latter another end flange, and said other end flange carrying said cutting means for cutting the filamentary material which is directed onto the empty spool.
 7. The combination of claim 6 and wherein said flange of said auxiliary spool has a smaller diameter than the end flange of said empty spool which is common to the latter and said auxiliary spool.
 8. The combination of claim 7 and wherein an adjusting means coacts with said cutting means for adjusting the latter radially with respect to said auxiliary spool along the flange of the latter which is distant from the common flange.
 9. The combination of claim 8 and wherein said auxiliary and empty spools both have cores of the same diameter.
 10. The combination of claim 9 and wherein the spool which has just been filled is identical with the empty spool which is about to be filled and also has an auxiliary spool extending from an end thereof, and all of the structure of said empty spool and the controls coacting therewith being duplicated for the other spool so that when the empty spool has almost been filled all of the operations can be repeated in the reverse direction with a new spool which replaces the filled spool.
